Procedure

To a solution of 1,1-dimethylethyl ((1R)-2,2-dimethyl-1-{[(6-{[4-methyl-3-(methyloxy)phenyl]oxy}-3-pyridinyl)amino]carbonyl}propyl)carbamate (Intermediate 96, 8.2 mg) in dry dichloromethane (0.5 mL) cooled to 0° C., TFA (57 μl, 0.740 mmol) was added dropwise and the solution was stirred for 3 hours at that temperature. The volatiles were evaporated. The residue was dissolved with dichloromethane (2 mL) and an aqueous saturated solution of NaHCO3 was added (4 mL). The layers were separated and the aqueous layer was extracted twice with dichloromethane. The gathered organic layers were dried over sodium sulphate and evaporated to afford the title compound (6.2 mg).
